Disp fx of nk of 1st MC bone, r hand, 7thG

This diagnosis code indicates a break in the neck of the first metacarpal bone (thumb) of the right hand, where the bone fragments are no longer in their normal alignment. The patient is in a later stage of healing, and the fracture is not progressing as expected, suggesting a delayed union.

This code is appropriate for follow-up encounters for a right thumb metacarpal neck fracture that has been previously treated but is now demonstrating delayed healing. This would include situations where the physician is monitoring the slow progress of bone consolidation, adjusting treatment plans due to non-union concerns, or performing procedures related to the delayed healing.

• Ensure documentation clearly specifies "right hand" and "first metacarpal neck" with displacement.
• The "G" seventh character signifies a subsequent encounter for a fracture with delayed healing; do not use for initial treatment or routine follow-up of a healing fracture.
• Always review the physician's notes for explicit mention of delayed healing or non-union concerns to justify the "G" seventh character.
